RKIN OnliPure Countertop Reverse Osmosis System Overview
The RKIN OnliPure is a Reverse Osmosis countertop system, which means that you won’t need to connect it directly to the water line like in most RO systems, making the installation process a breeze.
You just need to place in your countertop and connect it to an electrical outlet, and the system is ready to use, as you only need to fill the removable tank with one gallon of water and press the button to start the filtration process.
This filtration process is highly efficient, and the system only wastes one gallon of water for one gallon of water filtered, and it’s capable of removing up to 99% of contaminants reducing the TDS to almost 0.
So, if you are looking for a Reverse Osmosis countertop system, the RKIN OnliPure Countertop is one of the best choices you can make.
RKIN OnliPure Countertop Reverse Osmosis Filtration Capabilities
The RKIN OnliPure Countertop Reverse Osmosis system’s main focus is to reduce the TDS virtually to zero, removing up to 99% of all water contaminants, such as chlorine, lead, heavy metals, VOCs, fluoride, PFOA, PFOS, and many more.
This rate of contaminant removal is only achieved through a highly effective Reverse Osmosis filtration process combined with other filtration methods. The RKIN OnliPure Reverse Osmosis system contains 4 filtration stages, that work as explained below:
- Stage #1: a 5-micron sediment filter uses its outer layer to remove larger particles and its inner layer to remove smaller particles, effectively reducing contaminants like sediments, sand, rust, and suspended solids
- Stage #2: a coconut-based activated carbon block filter uses its adsorption capacity to remove contaminants like VOCs, chemicals, THM’s, disinfection by-products, bad taste & odors, etc.
- Stage #3: the core of the system, a Reverse Osmosis membrane removes almost to 0 the water TDS (total dissolved solids), removing nasty contaminants like heavy metals, fluoride, nitrates, hormones, bacteria, and many other contaminants
- Stage #4: finally, a post filter with ion-exchange media gives a final polishing to the water removing any bad odors and impurities from it
Unlike other RO systems, the RKIN OnliPure does not remineralize the water adding back minerals to it, as its focus is removing all particles from the water.
If having more alkaline water is important to you, you can consider a similar product from RKIN, the RKIN AlcaPure Countertop Reverse Osmosis that is basically the same product, the only difference is that on the last filtration stage it has a remineralization filter.
